Checkups, scans and tests during pregnancy

As part of your antenatal care you will be offered a number of check-ups, tests and scans. Some tests are offered to every woman as part of normal antenatal care in Australia. Other tests will be suggested if you or your baby have a higher risk of problems or are experiencing any concerns during the pregnancy. You don’t have to do any recommended tests if you don’t want to — it’s your choice.

Many problems can be detected before your baby is born, but not all of them. There are two main types of test offered during antenatal care:

Screening tests, which will let you know if your baby has a higher risk of having a problem, but can’t confirm the problem for sure
Diagnostic tests, which show whether your baby has a problem, with a much greater level of certainty

Your check-ups and tests may be done at a hospital, doctor’s clinic or somewhere else in your community, depending on whether you’re having your baby in a public or private hospital, a birthing centre or at home. This may also determine whether your check-ups are done by your GP, midwife or obstetrician.

The timing and number of some of the visits and tests listed below may change slightly depending on the antenatal care you choose, if you’ve had a prior pregnancy and if you are having any problems.
Here are the check-ups, tests and scans you would usually be offered if you have an uncomplicated pregnancy:

First visit

Confirmation that you are pregnant
Calculating how many weeks your pregnancy is and when your due date will be. You may be offered an ultrasound scan if the date is not clear.
Blood pressure, height and weight
Full blood test, to check your blood group and test for anaemia, rubella immunity, hepatitis B, hepatitis C, syphilis, chlamydia and HIV
Urine test, to see if you have a bladder or urinary tract infection
Screening for Down syndrome
Cervical screening to check for human papillomavirus (HPV) and/or any signs of cervical cancer
If at risk of vitamin D deficiency, a test for this may be offered

As part of your check-up, you will usually also discuss with your doctor or midwife:

Which medications you are taking
Whether you smoke or drink alcohol
Whether you would like an influenza (flu) vaccination
Which vitamin and mineral supplements you can take or should avoid
Antenatal care options available to you
Where you can get further information and antenatal classes

As well as the tests, scans and check-ups listed above, your GP, midwife or obstetrician may offer further tests, depending on your risk factors and circumstances. These can include:

Chorionic villus sampling (CVS), where a small amount of the baby’s placenta is collected to test for chromosome problems such as Down syndrome or other abnormality. This is usually done between 10 and 11 weeks of pregnancy, or at another time if a problem is suspected.
Non-invasive pre-natal testing (NIPT), which is a very accurate test to detect Down syndrome and certain other abnormalities. It is performed between 11 weeks and 13 weeks and 6 days of pregnancy.
A nuchal translucency scan, which looks at the back of your baby’s neck to assess the risk of your baby having Down syndrome. This test is done between 11 weeks and 13 weeks and 6 days, and may be conducted at the same time as the dating ultrasound.
Amniocentesis, where a small amount of amniotic fluid (fluid around the baby) is collected to test if the baby has a chromosome problem or other abnormality. This is usually done at 15-18 weeks, or at another time if a problem is detected.
